Just finished the p/s pump rebuild last night, I changed all the O rings and gave it a good cleaning. I re-installed and bleed all the air out of the system. BUT I can't get rid of the steering wheel shudder, I went through the proccess to remove all air 3 times last night, and just finished doing it twice today too. Still I have steering wheel shudders when turning. Anyone else experience this after rebuild? I am thinking that maybe the Dash-37 was not thick enough, but I would think if thats the case I would see air bubbles still in the reservoir. My pump had no issues before rebuild other than a leak cause by a warn out O ring. I think I may pull pump off again and replace the new O rings with the originals that aren't broken. Any advice is welcome and appreciated.
